Microsemi – Audio processors streamline implementation of two-way HD voice

microsemi
Designed for High Definition (HD) voice applications, Microsemi’s ZL380 TimberwolfTM series of audio processors enable the streamlined development of IP cameras with two-way hands-free audio capability.

The ZL380 devices feature the Microsemi AcuEdgeTM technology. This is a set of complex algorithms which allow the user to extract information efficiently from a stream of incoming audio signals. Microsemi’s AcuEdge technology integrates advanced features and dedicated firmware to deliver high-quality hands-free voice performance while reducing system design complexity. While most solutions deliver only half-duplex operation, Microsemi’s proprietary algorithm is able to continuously converge and track changes in the echo path to support full- duplex operation during double-talk situations.

Microsemi also helps system designers to accelerate their time to market by providing validated reference designs and easy-to-use development tools, including the Microsemi Audio Interface Box kit, which uses the MiTunerTM GUI software.

Features:
• DSP with voice-specific hardware accelerators
• Delta-sigma DACs with output sampling up to 48kHz and internal output drivers
• Single digital microphone input supporting one or two microphones
